The FINANCIAL — The study, published today in Psychological Medicine, reveals that 20% of those born in 1970 – part of Generation X – 19% of Baby Boomers born in 1946, and 15% of Baby Boomers born in 1958, experienced their highest ever levels of psychological distress in adulthood when they were in their 40s and 50s, including symptoms of depression and anxiety.
The researchers based at the Centre for Longitudinal Studies at UCL Institute of Education’s (IOE) Social Research Institute analysed data collected over the past four decades on more than 28,000 adults who are participating in three of Britain’s birth cohort studies. They examined participants’ reports of their mental health between the ages of 23 and 69 to investigate rates of psychological distress during adulthood, and how they differed across generations.
Among those born in 1958 and 1970, rates of mental ill-health decreased from their early 20s to their early 30s, then for all three cohorts, the prevalence of psychological distress increased from their early 30s to reach its highest levels in midlife – when participants were aged between 46-53.
The 1970 cohort consistently had the highest rates of mental ill-health during adulthood. At age 26, 16% reported psychological distress, before rates fell to 14% at age 30. Prevalence of mental ill-health increased to 16% at age 34, then to 19% at age 42, before reaching 20% at age 46.
For those born in 1958, prevalence decreased from 10% at age 23 to 8% at age 33, before rising to 13% at age 42, then increased again, to 15% at age 50. For those born in 1946, rates of psychological distress increased steadily during adulthood, from 6% at age 36, to 12% at age 43 and then 19% at age 53.
Among those born in 1946, rates of psychological distress were observed to decline as they reached their 60s. Prevalence of mental ill-health decreased from 18% at age 60-64 to 15% at age 69.
Across all three cohorts, at all ages, rates of psychological distress were higher among women than men. For example, in midlife, 23% of women born in 1970 had mental health problems compared to 17% of men. Among the Baby Boomers in middle age, 19% of women born in 1958 had psychological distress compared to 11% of men, and of women born in 1946, 24% had mental ill-health, compared to 14% of men.
Co-author, Professor George Ploubidis (UCL Centre for Longitudinal Studies) said: “Thanks to longitudinal data collected from almost 30,000 adults over the past four decades we can examine the trajectory of mental ill-health across two generations since the early 1980s.
“Midlife tends to involve a ‘peak’ in career, with middle-aged adults acquiring increasing responsibility as the ‘decision-makers’ in society, which is accompanied by reduced leisure time, and elevated job-related stress. Middle age is also often associated with changes to family structure, which may be linked with mental health, such as empty nest syndrome and rising rates of divorce. As people approach their 50s, they are also more likely to be parents and simultaneously care for ageing parents. The added pressures of the COVID-19 pandemic may therefore have a more pronounced detrimental effect on the mental health of middle-aged adults as many have increased responsibilities, such as homeschooling their children and caring for older and vulnerable relatives.
“Generation X were more likely to have psychological distress than the Baby Boomers across their lives. They entered the job market in the late 1980s and early 1990s during a period of recession and high unemployment, and also found it more difficult than earlier generations to get on the housing ladder. As a result, these particular circumstances may have had a lasting effect on the mental health of this generation throughout adulthood.”
Co-author, Dr Dawid Gondek (UCL Centre for Longitudinal Studies) added: “Mental health in adolescence and older age tends to gain much more attention than psychological distress in middle age, despite adults being particularly vulnerable to mental ill-health at this stage of life. Our study suggests that increased attention should be paid to the detection and management of mental health in middle age, for instance in primary care. It also implies the need for increased public awareness of psychological problems during midlife.”
